First of all I would stay off social media! Do not even think about her at all ! Hang out with your friends or family or venture into some new hobbies! Maybe get a makeover pamper yourself !
For me I have a lot of friends and have a huge family who would never allow me to wallow in self pity or ever be sad for too long. So I am able to stay positive and happy. Try new things get re aquainted with your gmail or friends. And remember you are the prize

I needed to hear that. Thank you!

* my love and I are happier than ever**

Only when you assign meaning to a neutral thing will you give power to that thing.

When you see a picture of him with someone else, just see it as is. Don't assign meanings, don't assign labels, don't wonder, don't assume, etc. I made this mistake before and it manifested in my reality.
